I just ordered a E90 M3 w/ ZP2,ZCP, looking for some enthusists in the FT Bragg area. Upgrades will include evo underdrive pully, UUC SS, DSSR, Hamann Roundels, Hamann racing shifter, pedals, handbreak handle, floor mats, and AFE CA, and still undecided on software. Looking at ESS or Dinan, any comments on which one is better?
